Understanding Violent Extremism: Messaging and Recruitment Strategies on Social Media in the Philippines
2018Article
Violent extremist activity on social media in the Philippines is a relatively new phenomenon in the complex conflict environment that exists in the southern part of the country. The rise of online violent extremism emerged despite the Philippines’ significant strides in the Mindanao peace process. The 2014 Comprehensive Agreement on the Bangsamoro between the government and the MILF was a landmark achievement. Yet a number of armed groups rejected the deal, many of which are now engaged in online extremism. The apparent affiliation of these groups with issues beyond Mindanao and the Philippine state signaled a potential new era of conflict in the country. With these concerns as a backdrop, The Asia Foundation and Rappler worked together to explore how young Filipinos interact with social media networks, and look into the prevalence and characteristics of violent extremist messaging and recruitment in the Philippines in 2018.
Media And Information Literacy - Reinforcing Human Rights, Countering Radicalization And Extremism



The MILID Yearbook is a peer-reviewed academic publication and a joint initiative of the UNESCO-UNAOC University Cooperation Programme on Media and Information Literacy and Intercultural Dialogue (UNESCO-UNAOC-MI-LID-UNITWIN), and the UNESCO-initiated Global Alliance for Partnerships on Media and Information Literacy (GAPMIL). The cooperation programme was launched in 2011 within the framework of the UNESCO University Twinning Programme (UNIT WIN). The MILID University Network now consists of 22 universities from all regions of the world. The MILID Yearbook 2013, 2014 and 2015 have been published in cooperation with the Nordic Information Centre for Media and Communication Research (NORDICOM). This year, the UNESCO has stepped in for this noble cause. It is high time to place media and information literacy (MIL) at the core of instruction at all levels of formal education, and it needs to be promoted in non-formal and informal educational setting as well. MIL can effectively contribute to enhancing intercultural dialogue, mutual understanding, peace, promote human rights, freedom of expression, and counter hate, radicalization and violent extremism. In fact, MIL is fundamental to producing knowledge for critical thinking, democratic citizenship, independent learning and good governance. The objectives of the Yearbook are to:• Strengthen and deepen the knowledge concerning Media and Information Literacy and Intercultural Dialogue (MILID) on global, regional and national levels including in the frame of human rights, dialogue, democracy and peace• Widen and deepen the collaboration and exchange between academics and partners on media and information literacy• Visualize and stimulate research and practices within as well as outside the MILID UNITWIN Network in the field of MILID while promoting a more holistic perspective of Media and Information Literacy (MIL).In addition to these overall aims, the MILID Yearbook seeks to address current issues which are connected to the overall themes of media and information literacy and intercultural dialogue. The year 2016 being the first year of the implementation of the sustainable development goals has provided an opportunity to examine the renewed emphasis on Human Rights-Based Approach to development. Further, the increased levels of national and global conflicts, as well as the new forms of violent extremism and radicalization have led to questions on the role of MIL in this global environment.

Generalized Gelation Theory Describes Onset of Online Extremist Support
2018 Manrique,P., Zheng, M., Cao,Z., Restrepo, E., Johnson, N.F.Article
We introduce a generalized form of gelation theory that incorporates individual heterogeneity and show that it can explain the asynchronous, sudden appearance and growth of online extremist groups supporting ISIS (so-called Islamic State) that emerged globally post-2014. The theory predicts how heterogeneity impacts their onset times and growth profiles and suggests that online extremist groups present a broad distribution of heterogeneity-dependent aggregation mechanisms centered around homophily. The good agreement between the theory and empirical data suggests that existing strategies aiming to defeat online extremism under the assumption that it is driven by a few “bad apples” are misguided. More generally, this generalized theory should apply to a range of real-world systems featuring aggregation among heterogeneous objects.
Down the (White) Rabbit Hole The Extreme Right and Online Recommender Systems
2014 O’Callaghan D., Greene D., Conway M., Carthy J. and Cunningham P.VOX-Pol Publication
In addition to hosting user-generated video content, YouTube provides recommendation services, where sets of related and recommended videos are presented to users, based on factors such as co-visitation count and prior viewing history. This article is specifically concerned with extreme right (ER) video content, portions of which contravene hate laws and are thus illegal in certain countries, which are recommended by YouTube to some users. We develop a categorization of this content based on various schema found in a selection of academic literature on the ER, which is then used to demonstrate the political articulations of YouTube’s recommender system, particularly the narrowing of the range of content to which users are exposed and the potential impacts of this. For this purpose, we use two data sets of English and German language ER YouTube channels, along with channels suggested by YouTube’s related video service. A process is observable whereby users accessing an ER YouTube video are likely to be recommended further ER content, leading to immersion in an ideological bubble in just a few short clicks. The evidence presented in this article supports a shift of the almost exclusive focus on users as content creators and protagonists in extremist cyberspaces to also consider online platform providers as important actors in these same spaces.
The Supremacy of Online White Supremacists – an Analysis of Online Discussions by White Supremacists
2015 Wong, M.A., Frank, R. and Allsup, R.Journal
A content analysis was conducted on five different white supremacist online forums to observe the discourse and types of activities occurring within. In addition, web link analysis was conducted on the forums to identify the presence of external links being posted and discussed by members. We found that members used the forums primarily for information provision, recruitment and networking. Based on these results, we discuss the implications that online hate speech have within offline settings, and the affects these activities have on Canadian citizens in light of the recent repeal of section 13 of the Canadian Human Rights Act (1985), the primary tool in Canada with which to deal with hate speech and other activities observed. The insights extracted from this research have provided novel insight into the sentiments and activities of the white supremacist movement online, a relatively unexplored venue of hate speech and propaganda online.
Anders Behring Breivik’s use of the Internet and social media
2013Aasland Ravndal, J.Article
Did the Internet play a decisive role in Anders Behring Breivik’s violent radicalization? It has proven difficult to understand if and how the Internet influences radicalization processes leading to political violence (Conway 2012). The Internet constitutes only one out of a wide range of factors with a potential influence on radical and violent behavior. We also lack detailed empirical data about the online lives of modern terrorists.

The case of the Norwegian far-right terrorist Anders Behring Breivik offers unique insights into the online activities of a terrorist who used the Internet and social media in almost every thinkable way. Not only did Breivik compile his 1516-pages long compendium based exclusively on Internet sources. Before the attacks, he was also an active discussant on a number of mainstream and extremist Internet forums, and a highly dedicated online gaming enthusiast.

This article reviews new sources on Breivik’s Internet adventures and road to militancy. It is primarily based on Breivik’s original posts and comments on various Internet discussion forums between 2002 and 2011.[1] In addition, Breivik’s trial hearings introduced a wealth of new information regarding his use of the Internet.[2] Finally, the article draws on a collection of Breivik’s private e-mails which was forwarded by Norwegian hackers to a Norwegian journalist six days after the terrorist attacks. A synthesis of the more than 7000 e-mails was later published as a book (Stormark 2012).

A key finding in this study is that Breivik likely never discussed his terrorist plans with anyone online. Moreover, his comments on various Internet forums do not stand out as particularly when compared to typical far-right online discourse. In other words, Norwegian security authorities would likely not react to his online postings even if he was being monitored.

Breivik’s online posts also indicate that his critical views on Islam and socialism had been established long before the so-called counterjihad blogs were created. This means that these blogs may have played a less decisive role for Breivik’s early radicalization than assumed by many. Later on, however, these blogs certainly strengthened Breivik’s radical thinking, although they come across as far less radical than his own ideological statements after 22 July.[3]

Breivik’s e-mail correspondence shows that he first and foremost wanted to become a professional author and publisher. He proposed to establish a so-called cultural conservative paper journal together with Norwegian bloggers he admired, who were also critical of Islam and multiculturalism. He also tried to impress the Norwegian blogger Peder Are Nøstvold Jensen, better known as Fjordman, with his book project, but was given a cold shoulder. The fact that he was rejected by several of the people he looked up to may have had a decisive influence on his violent radicalization.

Breivik gathered all the necessary information to build his bomb online. He also financed the terrorist attacks through an online company, and used the Internet, in particular e-Bay, to buy materials such as body armor, weapons components and bomb ingredients. Breivik also systematically used social media platforms such as Facebook and Twitter for propaganda purposes.

Finally, Breivik was an extremely dedicated online gaming enthusiast. Playing online games dominated his daily life during the years leading up to the attacks. One cannot dismiss theories that the extreme amount of time spent on playing online games while being isolated from friends and relatives may have had an impact on his disposition to engage in extreme violence.

In the following sections, this article article describes Breivik’s use of the Internet and social media along four dimensions: (1) online radicalization, (2) online gaming, (3) online attack preparations, and (4) online propaganda.
Steganography and Terrorist Communications
2017Abdoun, A. and Ibrahim, J.Journal
Steganography is the art and science of
hiding the fact that communication is taking place by
hiding information in other information’ (Johnson).
According to nameless “U.S. officials and experts”
and “U.S. and foreign officials,” terrorist groups
are “hiding maps and photographs of terrorist
targets and posting instructions for terrorist
activities on sports chat rooms, pornographic
bulletin boards and other Web sites”. This paper
informs the reader how an innocent looking digital
image hides a deadly terrorist plan, which can
destroy the world just in a click of a mouse. It also
describes and discusses the process of secret
communication known as steganography. The
crucial argument here is that terrorists are most
likely to be employing digital steganography to
facilitate secret intra-group communication as has
been claimed. This is mainly because the use of
digital steganography by terrorist is both technically
and operationally dubious. The most important part
this paper discusses is that terrorist are likely to
employ low-tech steganography such as semagrams
and null chippers instead. It investigates the
strengths of image steganography and the reasons
why terrorists are relying on it so much.

Understanding ISIS Myth and Realities
2015Abrahms, M.Video
Published on May 29, 2015
This video was streamed live by DMAPLab MIGS on 26 May 2015.

The Islamic State, also known as ISIS or ISIL, has become a household name because it films its atrocities and posts them online thanks to social media platforms such as Twitter and YouTube.

Western countries and Arab states appear to be united and see the group as a threat to international peace and security. But what do we really know about ISIS? What should the international community do to cripple ISIS' on the battlefield?

Max Abrahms, professor of political science at Northeastern University and member at the Council on Foreign Relations, offers a unique perception of the relationship between the Islamic State’s propaganda and its success as an organisation.
Hashtag Palestine 2018: An Overview of Digital Rights Abuses of Palestinians
2019AbuShanab, A.Report


The report notes that in 2018, the Israeli government continued to systematically target Palestinians and the right to freedom of expression via the Internet. In the year 2018, Israeli authorities arrested around 350 Palestinians in the West Bank on charges of “incitement” because of their publications on social media.

7amleh – The Arab Center for the Advancement of Social Media launched its annual report on Palestinian digital rights for the year 2018. The report details violations by governments, authorities, international technology companies and Palestinian society.


The report notes that in 2018, the Israeli government continued to systematically target Palestinians and the right to freedom of expression via the Internet. In the year 2018, Israeli authorities arrested around 350 Palestinians in the West Bank on charges of “incitement” because of their publications on social media. The Israeli government also submitted a set of bills that would violate the right to privacy on the Internet, including the expansion of the Israeli Cyber Directorate. Additionally, the Israeli court has received greater power to remove content from social media platforms.

The report explains the amendment of the Electronic Crimes Law by the Palestinian Authority in April 2018. This law still grants various official bodies the authority to monitor content on the Internet, block sites and arrest Palestinians in the West Bank. Furthermore, Hamas in the Gaza Strip continued to arrest Palestinians opposed to its policies based on the unclear charge of “misuse of technology”.

According to data from SadaSocial, 505 cases of content removal or blocking of users occurred on social media platforms Facebook, Twitter and YouTube in 2018. GoogleMaps continues to discriminate against Palestinians by listing illegal Israeli settlements, but not Palestinian villages in Area C of the West Bank, or Palestinian villages in the Naqab which are unrecognized by Israel. PayPal services are still unavailable to some six million Palestinians living in the West Bank and in the Gaza Strip. Airbnb announced in 2018 that it would remove lists of properties in illegal Israeli settlements in the West Bank, but excluded East Jerusalem, while Booking.com said it did not intend to remove its lists from illegal Israeli settlements.

The phenomenon of gender-based violence online was documented in Palestinian society. According to a report by 7amleh and Kvinna till Kvinna foundation in 2018, one-third of Palestinian women in Israel and in the occupied Palestinian territories were subjected to violence and harassment in social networks online.
White Supremacists, Oppositional Culture and the World Wide Web
2005Adams, J. and Roscigno, V.J.Journal
Over the previous decade, white supremacist organizations have tapped into the ever emerging possibilities offered by the World Wide Web. Drawing from prior sociological work that has examined this medium and its uses by white supremacist organizations, this article advances the understanding of recruitment, identity and action by providing a synthesis of interpretive and more systematic analyses of thematic content, structure and associations within white supremacist discourse. Analyses, which rely on TextAnalyst, highlight semantic networks of thematic content from principal white supremacist websites, and delineate patterns and thematic associations relative to the three requisites of social movement culture denoted in recent research - namely identity, interpretational framing of cause and effect, and political efficacy. Our results suggest that nationalism, religion and definitions of responsible citizenship are interwoven with race to create a sense of collective identity for these groups, their members and potential recruits. Moreover, interpretative frameworks that simultaneously identify threatening social issues and provide corresponding recommendations for social action are employed. Importantly, and relative to prior work, results how how the interpretation of problems, their alleged causes and the call to action are systematically linked. We conclude by discussing the framing of white supremacy issues, the organizations' potential for recruitment, and how a relatively new communication medium, the Internet, has been cheaply and efficiently integrated into the white supremacist repertoire. Broader implications for social movement theory are also explored.
One Apostate Run Over, Hundreds Repented: Excess, Unthinkability, and Infographics from the War with I.S.I.S.
2018Adelman, R.A.Journal
Compared to the more spectacular elements of its media repertoire—the slick recruitment campaigns on social media, the artfully composed battlefield footage, the grisly executions—I.S.I.S.’s infographics may seem dull, even trivial. Indeed, these data visualizations have gone largely unremarked, eliciting more bemusement than serious consideration. Against the tendency to discount these images, however, I argue that when I.S.I.S. turns toward charts and diagrams to represent its operations, it launches a stealthy but substantial epistemological challenge to media outlets that depict it as backward and irrational and rely on command of information as an index of Western power. Comparing infographics produced about I.S.I.S. and those produced by the group, I demonstrate that, despite their obvious differences, both types of infographics evince common preoccupations. Like Western news sources, I.S.I.S. creates infographics to map attacks, plot territorial gains, tally and categorize casualties, and track the types of weapons deployed. News media and I.S.I.S. infographics diverge primarily in their affective resonance, as similar information signifies in radically different ways. Ultimately, by producing and circulating these infographics, I.S.I.S. renders simultaneously renders itself more and less intelligible to outsiders: encapsulating its story while confounding prevailing representations as it weaponizes information.
Using KNN and SVM Based One-Class Classifier for Detecting Online Radicalization on Twitter
2015Agarwal, S. and Sureka, A.Chapter
Twitter is the largest and most popular micro-blogging website on Internet. Due to low publication barrier, anonymity and wide penetration, Twitter has become an easy target or platform for extremists to disseminate their ideologies and opinions by posting hate and extremism promoting tweets. Millions of tweets are posted on Twitter everyday and it is practically impossible for Twitter moderators or an intelligence and security analyst to manually identify such tweets, users and communities. However, automatic classification of tweets into pre-defined categories is a non-trivial problem problem due to short text of the tweet (the maximum length of a tweet can be 140 characters) and noisy content (incorrect grammar, spelling mistakes, presence of standard and non-standard abbreviations and slang). We frame the problem of hate and extremism promoting tweet detection as a one-class or unary-class categorization problem by learning a statistical model from a training set containing only the objects of one class . We propose several linguistic features such as presence of war, religious, negative emotions and offensive terms to discriminate hate and extremism promoting tweets from other tweets. We employ a single-class SVM and KNN algorithm for one-class classification task. We conduct a case-study on Jihad, perform a characterization study of the tweets and measure the precision and recall of the machine-learning based classifier. Experimental results on large and real-world dataset demonstrate that the proposed approach is effective with F-score of 0.60 and 0.83 for the KNN and SVM classifier respectively.
Topic-Specific YouTube Crawling to Detect Online Radicalization
2015Agarwal, S. and Sureka, A.Article
Online video sharing platforms such as YouTube contains several videos and users promoting hate and extremism. Due to low barrier to publication and anonymity, YouTube is misused as a platform by some users and communities to post negative videos disseminating hatred against a particular religion, country or person. We formulate the problem of identification of such malicious videos as a search problem and present a focused-crawler based approach consisting of various components performing several tasks: search strategy or algorithm, node similarity computation metric, learning from exemplary profiles serving as training data, stopping criterion, node classifier and queue manager. We implement two versions of the focused crawler: best-first search and shark search. We conduct a series of experiments by varying the seed, number of n-grams in the language model based comparer, similarity threshold for the classifier and present the results of the experiments using standard Information Retrieval metrics such as precision, recall and F-measure. The accuracy of the proposed solution on the sample dataset is 69% and 74% for the best-first and shark search respectively. We perform characterization study (by manual and visual inspection) of the anti-India hate and extremism promoting videos retrieved by the focused crawler based on terms present in the title of the videos, YouTube category, average length of videos, content focus and target audience. We present the result of applying Social Network Analysis based measures to extract communities and identify core and influential users.
A War of Keywords: How Extremists are Exploiting the Internet and What to do About It
2016Ahmed, M. and George, FL.Report
This research centred on three layers of analysis: Firstly, understanding
the keywords, or search terms, people use to
find information on Google; secondly, looking at the data
demonstrating links going into a selection of known extremist
websites in order to understand their relationships
with other websites;
and thirdly, analysing the content of
Google search results pages to understand the placement of extremist and counter-narrative content within search results for relevant keywords. The areas of analysis represent
important aspects related to the broader internet and,
when combined, gave the opportunity to get a snapshot of
extremist content beyond the realm of social media.

The results produced by this multi-faceted approach provide
an overview of extremist content online and shed
much-needed light on the impact and effectiveness of online
counter-narrative efforts.
Social media and counterterrorism strategy
2015Aistrope, T.Journal
With the rise of Islamic State of Iraq and Syria (ISIS), the issue of domestic radicalisation has taken on renewed significance for Western democracies. In particular, attention has been drawn to the potency of ISIS engagement on social media platforms like Twitter and Facebook. Several governments have emphasised the importance of online programs aimed at undermining ISIS recruitment, including the use of state-run accounts on a variety of social media platforms to respond directly to ISIS messaging. This article assesses the viability of online counter-radicalisation by examining the effectiveness of similar programs at the US State Department over the last decade. The article argues that governments attempting to counter online radicalisation of their domestic populations must take seriously the significant shortcomings of these State Department programs. The most relevant issue in this regard is the recurring problem of credibility, when the authenticity of government information is undercut by the realities of foreign policy practice, and existing perceptions of hypocrisy and duplicity are reinforced in target audiences.

Now on Twitter, Facebook: Jihadi Media Foundation Fursan Al-Balagh
2013Al-Hadj, M.Report
Media foundations connected to jihadi groups and jihad-supporting organizations, which once released their productions – videos, statements, and more – over jihadi forums, have turned to social media websites, mainly Facebook and Twitter, because of these forums' inability to provide reliable means for communication, interaction, and publication due to constant and often lengthy disruption of their online presence. This report discusses official and unofficial jihadi media foundations' presence on Facebook and Twitter, and identifies the foundations' accounts and provide background information regarding their affiliation and activities.
